Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00164 | $0.05495 |
| Opus 5.5 | $0.00066 | $0.02198 |
| Sonnet 5.5 | $0.00033 | $0.01099 |
| Haiku 4.5 | $0.00016 | $0.00549 |
Grade A, and why
cometchat-flutter-v5-sdk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ground truth:
cometchat_calls_sdk5.0.7 from pub.dev + catalogflutter-calls-v5.json(the closed symbol list — 59 COMPILER-VERIFIED symbols; every type below is in it). Catalog built from the PUBLISHED package; at 5.0.7 it matches thecalls-coremonorepo exactly — but never infer that from a version string (references/docs-map.md§ "Upstream"). Official docs:/calls/flutter/**= v5 · Docs MCP. Fetch exactSessionSettingsfields, event names and signatures from the docs (references/docs-map.md) — never memory. ⚠️ The live pages carry ~56 symbols that DO NOT COMPILE, including the entire documented token flow — see "Doc corrections" below; prefer THIS skill's names over the page's. APPEND to the user's app — additive wiring only. This is the HEADLESS path (no UI Kit); for the prebuilt drop-in call UI usecometchat-flutter-v6-callsinstead.
Companion skills (read first)
- Standalone/headless entry — this skill owns its own package (the Calls SDK) and has no
-coresibling; self-contained for meet-style calling. - For 1:1 RINGING only it also drives the Chat SDK (
cometchat_sdkv5) for signaling — signatures fetched viareferences/docs-map.md(§ "1:1 RINGING"). It does NOT depend on the Flutter UI Kit. - Prefer the UI Kit instead? If the app also wants chat and a prebuilt call UI, use
cometchat-flutter-v6-core+cometchat-flutter-v6-calls— not this skill.
Use this skill when
"add calling from scratch / without the UI Kit", "standalone voice/video on Flutter", "build my own call screen", "headless calls SDK", "meeting-room join by session id", "one-on-one ringing". Precondition: the caller chose the from-scratch / standalone path (the "add calling" router asks this). If they want the prebuilt call UI, route to cometchat-flutter-v6-calls.
Prerequisites & install
# pubspec.yaml
dependencies:
cometchat_calls_sdk: ^5.0.7 # verified against 5.0.7
then flutter pub get.
1:1 ringing additionally needs the Chat SDK (cometchat_sdk v5) for signaling.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cometchat-flutter-v5-sdk is a skill published in the GitHub repository cometchat/cometchat-skills (150 stars, last pushed 6d ago), licensed MIT. It adds 164 tokens to every session and 5,495 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-12.
